This study investigated benzene destruction in flue gas, finding that increasing temperature from 850 to 973 K boosts benzene conversion from 55% to 99%. These findings offer valuable data for modeling benzene oxidation in waste incinerators.
Area of Science:
- Chemical Engineering
- Environmental Science
- Combustion Chemistry
Background:
- Benzene is a hazardous air pollutant requiring effective destruction methods.
- Flue gas treatment is crucial for industrial emissions control.
Purpose of the Study:
- To experimentally investigate the thermal destruction of benzene in methane/air flue gas.
- To provide experimental data for modeling benzene oxidation in waste incinerators.
Main Methods:
- Laboratory-scale atmospheric laminar flow reactor experiments.
- Operation at fuel equivalent ratios (phi) of 0.06, 0.1, 0.5, and 3.7.
- Temperature range of 850–973 K with a 5-second residence time.
- Gas chromatography (GC) and high-pressure liquid chromatography (HPLC) for stable-species analysis.
Main Results:
- Benzene conversion increased from 55% to 99% as temperature rose from 850 K to 973 K.
- Major hydrocarbon products identified include phenol, acetylene, formaldehyde, acrolein, methane, and acetaldehyde.
- Experimental data showed fair agreement with the Emdee et al. benzene model for benzene consumption and CO production.
Conclusions:
- Thermal destruction is an effective method for removing benzene from flue gas.
- Experimental data provides a basis for refining benzene oxidation models in waste incinerators.
- Further research is needed to improve sub-models for small hydrocarbon product prediction.
